Make sure the remote turn on cable is connected correctly and fuses on the amp are not loose. But first off jump power from the power terminal to the remote terminal to see if it even turns on. if it does not then the problem is something blown inside the amp. Is there a fuse under the hood? if so make sure it is not blown.

Hi, I own a lightning audio B300.4 amplifier, it is hooked to battery and grounded to boot with same. Remote cable from headunit is hooked up. All of these cables are in the right places and nothing else...


sounds like amp is grounded. use a multimeter with ohms and test from pos to neg, should be o.l if there is any reading or resistance there the amp is grounded and junk

Lightning audio b150.2 as soon as +12 is hooked up blows 25 amp fuse and the c2 1000uf/35v capacitors blow???????


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you.

RCA CABLES


RCA cables are the best way to get the audio from your head unit to the amp. If your head unit doesn't have RCA outputs, you might be able to use the speaker outputs of the head unit to connect to the "high power" or "high level" inputs of the amp, if the amp has such inputs (check your manual).

you need to get a fan for it because it does not come wit one and when you get the fan you have to hook it up from the inside by taking the torture tested/bolt sign off and look for a small white pug to attach it to

Then it's a bad ground. Where did you ground the ground cable to? Is it tight, free of rust, clean, and most importanly, bare metal and free of paint?

Amp cuts off


So you have an EQ and a Pioneer amp you're trying to hook up to each other? And only some Stinger RCA cable works? And when the lightning audio RCA cable is hooked up, it doesn't turn on? The amp isn't grounding itself through the RCA cables, is it? Check your ground wire and make sure it has a clean contact that's free of rust or any paint that might be in the way. Otherwise, the RCA cables should have nothing to do with an amp turning on or not.
